- Be'it'lmown that l, GEORGE R.

Vcitizen of the United-States, residing at Wyandotte, countytaf Wayne,State of Michi gan, have inventada certain new and useful4Improvement.in`h Lanterns, and declare vthe lfollowing to bea full,clear, and exact de-V' scription of the same, such -as'will enableothers skillediin the art to whichit pertains form a part ofthis-specification. y

My invention` relates 'to an ynnproverne'nt` in` the ,general'construction of lanternsadapted to Vmanufacture"and burn acetylene gas;vthe same'being shown in the accompatrying-drawings and moreparticularly set claim. y

One of the objects of this inventionis to vliorth inthe followingspeeiiication and lsimplify the general construction, and tore-,lv

duce 'the cost of manufacture, by thefelirnifnationof a number of partsusually required i lin la lanternof this character. v I

One salient feature of the invention is-the elimination of the usual airvent opening into the water chamber, and the substitution of a passagebetween thegas .chamber and` the top ofthe water chamber that the'waterin the latter may be under pressure that it may fiow freely into' thecarbid chamber upon opening the valve controlling its dis-y charge. Theusual Avent isrobjectionableon signaling.

account of the water discharging or spillv ing through the opening whenthe lantern is swung or tilted, as required in railroad pressure of gasin the gas chamber which be relieved. l

Another feature of the invention'consi'sts in so constructing the baseof ,the lantern that it' may be employed as one'of the telescoping partslof the carbidstorage cham ber thus eliminating one part, it beingcustomary to construct the carbid chambers of two independenttelescoping members housed in the base of the lantern.

Another feature of the'nvention consists Specification ofLetters Patent.i

D Another -feature of the invention consists" 1n providlngmeans wherebyany excessive l' Patented Dec. 21, -1915. application me@ maken20,1915." sesamo, 15,698.

injoininglthe body 'of the lantern with the upper. structure atsa` pointdirectly above the'- carbid chamber by a -screw threaded connectionbetween thejbase and the'. water providing a gas storagechamberginterinelmate of "the water and carbid chambers,

urhichare spacedapart forthat purpose,l

scoping cupof the carbid chamber which serves 'toi-force thecup'directly uponthe carbid lto provide against its dislodgment, andrupon' disengaging the base from the water chamber above-the spring -maybe` .55:A chamber, thereby insuringa tight joint and A i used as abailfor the withdrawal of the invertedtelescoping cup to remove lor renewvthe carbid in the chamber.

" A' further'. object 'is thev meansl provided vfcr locking; the-lanternsupporting bail to .itsframe that it'i'nay be used for railroad v signalpurposes, the1T construction however an ordinary swinging lantern.

providing for lits ready release `for vuse as Other advantages andimprovementswill l hereafter appear;y l In the drawings accompanyingthis specilication:-Figure 1,is an elevation partly in section of alantern embodying mv invention. Figli is la'detail View' of a frag-jmentary portion ofthe lantern .bail 'and its'i supporting bracket.

Referring now to the iettferscf'reference placed noon Athe drawings :A,`denotes the base ofthe lantern forming also one portion of the carbidchamber B.

C, is an invefrtedcup-shaped element tele-- scoping in thel ,carbidchamber B, and adapted to bearl upofh the carbidcontained therein thatit may not bevdisplaced with the .swinging of-the lantern. rlhe upperedge of the base portionA, is threaded to engage the screw threadedflange d, of the water cha1nber' D.

D, is a tube extending downwardly from the water chamber "into a slottedtube E, sleevedlrifrnthe depending fla-nge c, of the inverted cup-shapedcarbid member.

F, isa tube opening into the water cham- .tip or other gas burner H.

I, is a tube opening into-the depending lower wall J2 -being'instaggered relation toy the aperture `1n the baille-plate above, that`ber and extending into the tube D its lower endbeing formed with avalve seat f, under -control of the needle valve F.

F2, is a swinging arm secured to the stem of the valve I4", by which thelatter may be adjusted to discharge water from the water chamber intothe depending tube D. The

water passes, thence out through theslots of the'telescoping tube E intothe carbid chamber' generating a gas upon contact with the carbid, whichpasses to the gas chamber G through the ports c', in the wall of theinverted cup.

H, is a tube opening into the gas chamber G, and extending up throughthe water chamber, its' top being fitted with a lavatube D, and passingout through the water chamber with a return bend above opening into anauxiliary chamber J. The auxiliarv chamber is divided by a perforatedbaffleplate J its lower wall entering.,r the space above the waterchamber which is provided with an aperture for the delivery of gas intothe water chamber, the aperture in the the water in the chamber may noteasilv be discharged through the. apertures through swinging of thelantern. ',K, is an 'imperforate filler cap by removing which the waterchamber may be lled..`

L, denotes a vent tube opening into the gas chamber and projecting down'through the base of the lantern its end beingl closed by a screwthreaded cap L having a transverse opening L2, which may be adjusted toprovide avent for the gas chamber to relieve any excessive pressure. y

L3, is a stop to limit the adjustment of the cap and to insure againstits loss or displacement.

.M, denotes the usual globe supported upon the ledge `j, formed in thewall of the water chamber. y

N, is a cowl perforated for ventilation supported by the globe guardframe N.

O, is a bail pivoted to the ears fn., n, of the guard frame, one arm ofthe bail being flat- .I

tened as indicated at O, and slotted as at 0.2,

t0 form tines O3, adapted to project on either side of the ear n, ofthe' frame when attached to the inner face of the latter.

vided for signal purposes, but should it be ldesired to convert thelantern into one having a swinging bail it is only necessary todiseugage the pivot bolt P, and connect the bail O2, to the outside ofthe ear n, replacing. l

the pivot bolt,-it being obvious that the bail is then free to swingwith respect to the guard frame. The cowl is fitted onthe inside with aspring Q, adapted to bear against the upper `wall of the cowl at one endand at lantern having a rigid bail may thus be prothe other end againstya cross member Q resting upon the top ofthe globe M, where-ll by thelatter is held against displacement.

Having indicated the several parts by 'reference letters the.construction and operationof my `device willbe readily understood. j 1

The inverted cup inthe base of the lantern is first removed and filledwith carbid, the

cup lis then placed in position and the base is screwed to thedownwardly projecting flange of-the water chamber. The cap K, is thenremoved from the water chamber and the latter charged with water t0 asuitable height. The globe is then replaced and the valve F adjusted topermit the passage of water from the water chamber ,to the valve tubeleading into the depending tube D, from whence it passes through theSlotted telesc'oping. memberofthe carbid chamber and out into thelatter. t'ailto freely ow from the water chamber when the lantern isinitially lighted, the cap L, of the vent tube may be adjusted to admitair which will serve to relieve the air bound condition of the waterchamber.

vent tube may be closed the gas passing up through the burner tube 'H4for ignition,-`

a. portion of thegas flowing through the pipe I, by way of the`auxiliary chamber J, into the water chamber providing pressure toassist in the discharge of the .water therefrom by way of the valvecontrolled dis*-l charge port f.. If the formation o'f gas is too rapid'or' the pressure excessive causing Ithebur'ner to blow the vent pipe L,may

be opened bythe adjustment of the cap to temporarily relieve theexcessive pressurein the gas chamber, it may then be closed: 4It willalso be obvious that a proper'adjustment of the valve F controlling thedelivery Should the water .Immediately upon the formation ofl gas the iof water to the carbid chamber will serve to govern thevolume andformation of gas de-y no the carbid chamber throughapertures formed 1nthe inverted cup shapedl member, a spring between the inverted cupshaped member and the' water chamber, a tube depending from the waterchamber Aand extending through the inverted cup shaped member, a slottedtube, depending from the*-.i,nv,ertel` cup shaped member and embracingthe firstnamedv tube,'a valved passage between the iso Water chamber andthe first named-tube, a
